METHOD OF TAKING UP WEAR IN BEARINGS.

Application filed March 7, 1921. Serial No. 450,215.

To all whom it may concern:

Be itknown that 1, CHARLES A. MILLER, a citizen of the United States, residing at Longville, parish of Beauregard, State of Louisiana, have invented a certain new and useful Improvement in Methods of Taking Up ll ear in Bearings, of which the following is a full, clear, and exact descrlptlon, such as will enable others skilled in the art vto which it appertains to make and use the same, reference being had to the accompanying drawings, form1ng part of'this specifi- 4 cation, in which- Figure 1 is a sectional view through a radius rod socket bearing showingmy improved reaming tool in operative position relative thereto.

Figure 2 is a detail view of the ball and socket, connection between the radius rod and the bearing on the engine casing.

Figure 3 is a sectional viewthrough the radius rod bearing reboredwith the liner inposition therein. p

'Fig'ure"4 is a detail view of the liner.

Figure. 5 is a sectional view showing a modified form of liner.

Figure 6 is a detail view of the liner shown in Figure 5. Figures =7 to 9, inclusive, represent detail views of a modified form of my inven tion.

Figure 10 and 11 are similar views of another modified form.

This invention relates to a new and use, .ful improvement in bearings for radms rods as used in a' well known commercial type r of automobile, the object being to rebore thee-bearing" when worn'so that it .will be made of such size as to receive a liner, preferably formed of pressed metal, which? liner will take up the Wear-in the original bearingand prevent rattling of the parts inci dent to a loose joint connection'between-the machine.

radius rod andthe engine casing;

My invention also contemplates the of -an improved form of reaming tool for reboring'thebeari'n' of-the engine casing,

said tool being capa le of. manipulation in such a manner as to not require the removal of the, engine casing from 'the chassis of the Inthe drawings, 1 indicates an ordinary radius rod and -2.the ball at the converging ends thereof. This radius rod, as' is well known, is connected to the front axle of a machine and issubject to vibration,

particularly when the machine is passing over rough roads, and this vibration will cause the ball 2 and the socket bearings which receive it to become worn. Usually,

' the greatest wear occursin the socket bearmotion in this connection and considerable noise results from the rattling of the loose 'oint. i

J The socket bearing 3, which is secured to the engine casing, is provided with two threaded bolts 4 and ordinarily a cap piece' 5, provided with perforated lugs or wings through which the bolts 4 pass, is used to hold the bolt 2 in position, this cap piece 5 being held against the socket 3 by means of nuts 6 and wear take-up and anti-rattling springs 7. It is, of course, obvious that the cap piece 5 canberenewed at little cost. when worn, but where considerable wear exists in the socket bearing 31 propose to rebore this socket bearing bymeans of a rose reaming head 8, mounted on the upper end of a shaft 9, the lower'end of said shaft-being formed rectangular in shape so as to receive a wrench (not shown) by which the reaming tool may be operated.

10 indicates a sleevelooselymounted on the shaft 9, the lower end'of which sleeve is preferably provided with-a knurled surface 10", while its upper end is threaded to engage anut 11.v This nut 11 is provided with perforated lugs or wings registering with the bolts t; When the nut 11 is secured 1n posltion against the socket bearing 3, the same as if the cap piece 5 were secured in position, saidnut is held in fixed relation to said socket bearing.

r; Washersl12 are arranged between the ends of the sleeve 10 and. the reaming head 8.

After the ni1t L1 is secured in position, the

s1eeve-10 1s rotated so as to bring. the ream- V 1ng tool into contact with the semispherical seat in the, socket Hearing 3, then a wrench is applied tothe lower-end of shaft ,9, and said shaft-and its. carried reaming tool are rotated with one hand while the sleeve 1 is fed forward with the other, and consequently the operator can rebore and enlarge the semispherical bearing in the socket bearing 3. When the lower flat face of the reaming head 8 is flush with the lower face of the socket bearing 3, which the operator can readily determine by looking through the opening through which passes the hank 01' the radlus rod, the reaming tool may be Withdrawn and the nut 11 removed.- The liner bearing 13 (shown in Figiires 3 and 4) preferably made of pressed metal having perforated lugs or wings 13*, is now placed in position on the underside of the socket bearing 3. The socket bearing 3 having been rebored to such a .size as to accommodate the semispherical projection on the liner bearing 13, will, when said liner bearing is'in position, lower the point of attachment of the brace to the engine casing approximatelythe thickness of the wings 13". This I deem unimportant. The

when the socket bearing mner surfac'e-or cavity-of the liner bearing will ordinarily compensate for all worn surfaces onthe old bearin and will make a. tight fit with the ball when the radius rod i'sagain placed in position and the cap 5 ap ied 11 Figures 5 and 6, I have showna wingless liner bearing 14 havinga projection 14 fiedform of my invention-in which a, semitruncated reaming tool is employed to enlarge the lower portion of the semispherical recesses 1n the socket bearing 3 so that a liner 16, such as shown in Figures 8 and 9,

may be employed. This bearing liner 16 is preferably made of forged metal and the upper convexity of its dome-like surface is struck up from the same center as the inner concavity of its bearing surface.

InvFigure 10, I have shown a liner 17 havingyja pin 18 to hold it in its central 1 position; and to avoid the necessity of providing the liner 17 with wings, as shown in Figure 8, I may use a' shim 19. The liner 1-7 is shown in detail in Figure 11. This "semi-truncated reaming head 15 is cheaper in cost and requires less power to operate than the rose; reamer 8, shown in Figure 1.

What I claim is:

1, A method of taking up wear-in a socket bearing of automobiles, the same consistin in attaching a nut in juxtaposition to sai hearing, operating a reaming tool through said nut to enlarge said bearing, removmg said nut and reaming tool, interposin va bearing liner into the rebored bearing and finally clamping the \connected parts together.

2. A method of taking up wear in a radius rodbearing for automobiles consisting in I first enlarging the bearing seat in situ, in-

troducing a bearing liner into the enlarged seat, and finally reassembling the parts constituting the bearing. In testimony whereof I hereunto afiix my signature this 5th day of March, 1921.
